little bit on the pre concentration study work.
first round has been successful in confirming br mineralisation amenability. but amenability to what?
going back to the mett test work done in ‘22 which planned work included comminution, flotation, projected flowsheet design and beneficiation analysis. with one of the main objectives to test whether the racecourse mineralisation is amenable to a simple flotation flowsheet.
skip forward to first round ore sorting/pre concentration done by tomra sorting solutions. where their test work was to also determine ore - waste separation characteristics from core samples that were already analysed.
the review by altrius recommended that further test work be carried out on pre-screening, gravity separation and co**** particle floatation with the cpf work is said to be progressing favourably.
would conclude then, that br mineralisation is amenable to flotation. we already know the lower grade ore is disseminated and not generally amenable to pre concentration such like tomra sorting, whereas cpf is not limited as such like most methods that require more distinct grade variability. cpf is also used as a scavenger tech in tailings to recover low grades.
if so then cpf is certainly looking likeliest to achieve the best overall results and most chance of going into the flowsheet design, 'if' the trade off against losses improves overall on the economics.
"to meet society's needs for critical mineral resources, the mining industry must develop projects that are socially accepted, environmentally sustainable, and economically profitable. one of the processes that have highest potential to overcome some of these challenges is co**** particle flotation"
hoping for positive enough results that firm decisions can be made going forward that maybe doesnt involve the need for more drilling
